Hands-On Geometry

Use this lesson plan to help your geometers develop informal proofs of the circumference and area of a circle. Working in small groups, students rotate between three stations to complete hands-on activities that illustrate the...

Your geometry learners will be pros at transforming figures using rotations and reflections after this hands-on instructional activity. Collaborative groups, with access to geometric construction tools, analyze and report the series of...

Learners explore two and three-dimensional objects with a hands-on approach and an element of chance. Groups choose the name of a solid figure from a "hat" and work with that shape. They sketch it, determine the number and shapes of...

Your learners will enjoy this conglomerate of hands-on activities and projects that can be used in algebra one and two, geometry, and personal finance. Rich in math standards, these projects reach into learners' lives to motivate and...

Searching for a detailed lesson to assist in describing rotations while keeping the class attentive? Individuals manipulate rotations in this application-based lesson depending on each parameter. They construct models depending on the...

This amazingly extensive unit covers a wealth of geometric ground, ranging from constructions to angle properties, triangle theorems, rigid transformations, and fundamentals of formal proofs.  Each of the almost-forty lessons is broken...

What does it mean for apples to have chirality? This and other explorations in geometry, such as tiling the plane, boxing a tetrahedron, and investigating Euclid's Characteristic, are included in this resource on Euclidean geometry....

This extensive chapter gives learners a new angle on that old geometry favorite, trigonometry. From the unit circle to right triangles, the role of trigonometric ratios is explored through explanation of theory and working application...

Connect algebra and geometry on the coordinate plane. The eighth unit in a nine-part integrated course has pupils develop the distance formula from the Pythagorean Theorem. Scholars prove geometric theorems using coordinates including...

As an introduction to the lesson, learners verify the Pythagorean theorem with a hands-on proof. Then, pupils use the theorem to determine whether three side lengths could form a right triangle and choose one of two real-life situations...
